Hamilton No. 7 "Bicycle Gun", .22 cal. single shot rifle. NSN. Mfg. 1900 in Plymouth, MI. A most unique little "boy's rifle" with all steel construction and nickel finish. The barrel is only 8" long (ATF has placed this gun in the C&R category) and cocks with a round knob just forward of the triggers. The barrel pivots left for loading. Very good condition with some corrosion on the stock parts. Maker's name/address and "No. 7" on inner buttplate. Rear tiny peep sight. Really cool little gun and will enhance any boy's rifle collection! C&R OK.
